The convention for naming a type of bundled fibers is X % N Y,
where X is the percentage of polyester (STAUD) relative to elastomer, and
Y is the number of individual fibers constituting the bundle. 

The filename convention herein is: X_percent_NY_specZ_P, where: 

X = the % of polyester in the SEFs used
Y = the number of SEFs in the jamming fiber 
Z = the specimen number 
P = the trial (1 through 12, explained below)

For each type of fiber given by unique X,Y, 3 specimens were tested. Each specimen was
tested by first starting at 0 and decreasing pressure to -60 kpa (trials
1-4), then going up from -60 to 0 (trials 5-8), and finally going from 0
back down to -60 (trials 9-12). This way we hoped to control for the
mullins effect across all pressures. To reiterate, an example of the full file convention reads:
60_percent_N4_spec2_4. This would represent a type of jamming fiber consisting of 4 individual
SEFs of 60 percent polyester, the second sample of that type, and
subjected to -60kpa.

An average was taken across the 3 specimens of each type at each pressure using mean() and standard deviation calculated using std() matlab functions to obtain the confidence clouds and average lines.
